------------------------------------------------+---------------------------
 slime 20080404 +app variant still has a library dependency on port:emacs.

 The app variant needs to "depends_lib-delete port:emacs" and "depends_lib-
 append port:emacs-app". Additionally, the workaround for Carbon Emacs
 needs to be moved to the "else" block of the "[variant_isset app]" test,
 because the "[registry_installed emacs]" line chokes if emacs is not
 installed.

 Furthermore, I don't know that this is specific to the slime Portfile, but
 while
 {{{
 sudo port install slime +app
 }}}
 does the Right Thing™ when the Portfile is patched by the attached diff,
 {{{
 sudo port upgrade slime +app
 }}}
 ignores the "+app" and starts downloading emacs-22.2.tar.gz as if
 port:emacs were still a dependency.
